Abstract

Media encryption technologies actively play the first line of defense in securing the access of multimedia data. Traditional cryptographic encryption can achieve provable security but is unfortunately sensitive to a single bit error, which will cause an unreliable packet to be dropped to create packet loss. In order to achieve robust media encryption, error resilience in media encryption can be treated to be equivalent to error resilience in media transmission. This study proposes an embedded block hash searching scheme at the decoder side to achieve motion estimation and recover the lost packets, while maintaining format compliance and cryptographic provable security. It is important to note that the proposed framework is a kind of joint error-resilient video transmission/encryption and copyright protection.
